INSULATOR RACK.

Application filed May -18, 1925. Serial N0. 31,059. g

This invention relates to certain new and useful improvements in insulator racks and has as one of its objects totprovide means for so mounting insulators as to permit their ready removal.

It is another object of this invention to generally improve the construction of insulator carrying racks in order to simplify their construction.

A further object of this invention resides in the provision of a rack proper and an insulator adapted to be inserted through an opening therein and having a part cooperat-.

ing with the rack to prevent rotation of the insulator. v

7 And a still further object of this inventio resides in the provision of improved means .preventing the accidental displacement of the insulator.

With the above and other objects'in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

In the accompanying drawing, I have illustrated several complete examples of the physical embodiment of my invention constructed according to the best modes I have so far devised for the-practical application of the principles thereof, and in which:

'Figure 1 is.a perspective view of an mproved insulator carrying rack embodying my invention, one of the insulators being about to be inserted in position;

Figure 2 is a view, partly in vertical sec tion and partly in elevation, illustrating a slightly modified form of rack.

Referring now more particularly to the accompanying drawing, the numeral 5 designates a rack which is preferably of channeled or inverted U-shape, having depending longitudinal flanges 6 and a transverse portion 7, which is apertured at intervals, as at 8, to receive insulators 9.

The insulators 9 may be of any particular construction and in the present embodiment tor, as previously described, to maintain the channel 10 and opening 11 in one plane and the insulator is secured against accidental detachment by one or more resilient fingers or tongues 14 struck from the rack adjacent the opening 8 and adapted to spring into notches 15 formed in the opposite sides of the insulator shank adjacent the head 12.

As will be apparent, the insulator is passed through the opening, 8 from the rear or channeled side, the spring fingers or tongues 14 riding over the insulator and snapping into the grooves 15 which register with the tongues when the flat surfaces 13 are in register with the flanges 6.

In Figure 2 a slightly modified form of my invention is illustrated in which the spring tongues or fingers 14; are eliminated and the insulator secured iniplace by bending inwardly the lower portion of the flanges 6 adjacent the heads 12 or bending in lugs formed thereon, as at 16.

The insulators areheld against rotation by the flat surfaces 13 in that form of my invention illustrated, which are formed by reducing opposite sides of the head.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art to which an invention of this character appertains that I provide'a very strong and efiicient insulator construction which is formed from any bendable material to thus reduce the cost of manufacturing.

What I claim as my invention is:

A device of the character described, comprising a rack formed of bendable metal stamped to channel shape and having an opening therein, an insulator adapted to be front face of the rack, and tongues struck from the face of the rack on opposite sides of the opening and adapted to snap in notches formed in the insulator sides when the insulator is in position.

In testimony whereof I afiix my signature.

WILLIAM D. KYLE.
